NGK CR7HIX Iridium Spark Plug

The special Iridium point, and the narrow electrode ensure optimum combustion. The CR7HIX is a "cold" spark plug, that is to say the most suitable for temperatures up to 20C °.

Iridium advantages:

• Iridium centre electrode (0.6mm diameter).
• Better ignition with less power needed.
• Higher performances compared to classic spark plugs.
• Taper Cut ground electrode (Better flame spread).
• 2 to 3 times more lifetime in comparison with standard plugs.
• Better stability.
• Less fuel consumption.
• Stronger accelerations / More reaction from the engine.
• Corrosion proof alloy.
• Cleaner combustion / Less unburned fuel.
• Easier cold start.
• Smooth Idle / Less vibrations

A spark plug cleaning can be done with a hard tooth brush with some brake cleaner or gasoline, never use a steel wire brush!
